The effects of Nd 3+ on the quality and quantity of volatile organic compounds (VOCs) in the leaves of Lycopersicon esculentum were studied. The results demonstrate that Nd 3+ can increase the total amount of VOC by 75% after treatment for 120 h, as compared with the control. Phyto-oxylipins, terpenoids and aromatic compounds were increased by 73%, 38% and 21%, respectively. (E)-2-hexenal, the most abundant constituent is increased by 74%, β-phellandrene and α-caryophyllene in terpenoids, eugenol in aromatic compounds are also enhanced significantly, and increase by 129%, 65% and 309%, respectively. Nd 3+ in different concentration can increase the production of VOCs and shows different trends in the time course of induction. There is also an increase in ·O-_2 formation, chitinase and β-1,3-glucanase activities in response to Nd 3+ treatment. These findings suggest that Nd 3+ may act as a potent agent to enhance the ability of L. esculentum against disease by increasing the production of VOCs.

The results demonstrate that Nd 3+ can increase the total amount of VOC by 75% after treatment for 120 h, (E) -2-hexenal, the most abundant constituent is increased by 74%, β-phellandrene and α-caryophyllene in terpenoids, eugenol in the surrounding compounds are also significantly increased, and increase by 129%, 65% and 309%, respectively. Nd 3+ in different concentration can increase the production of VOCs and shows different trends in the time course of induction. There is also an increase in · O-_2 formation, chitinase and β-1,3-glucanase activities in response to Nd 3+ treatment. These findings suggest that Nd 3+ may act as a potent agent to enhance the ability of L. esculentum against disease by increasing the product ion of VOCs.
